GOVERNOR-VALVE.

SPECIFICATION forming part of Letters Patent No. 706,616, dated. August12, 1902. Application filed June 27, 1901. Serial No. 66,281. (Nomodel.)

To all whom, it may concern:

Be it known that I, LESLIE J. WATSON, a citizen of the United States,residing at Port Huron, in the county of St. Clair and State ofMichigan, have invented certain new and useful Improvements inThrottling Governor The object of the invention is to provide agovernor-valve which is simple, cheap, and durable in construction,eificient in operation, and in which provision is made'for a ready andquick adjustment for controlling the speed of the engine.

With this and other objects in view the in vention consists of certainnovel features of construction, combination, and arrangement of parts,which will be hereinafter more fully described, and particularlypointedout in the appended claims.

The accompanying drawing shows a central vertical section of athrottling governor-valve constructed in accordance with myinvention.

Referring now more particularly to the drawing, the numeral 1 representsthe valvecasing, provided with the receiving and delivery pipes 2 and 3and the vertical hollow cylindrical valve-guide 4, which guide is incommunication with the receiving-pipe 2 and spaced from the oppositewall of the casing to provide a passage 5 for the flow of the steam tothe delivery-pipe 3. The lower end of the casing is closed,while theupper end thereof is open and is adapted to be closed in the usualmanner by a cap, (not shown,) having a stuffing-box through which slidesthe valve-stem 6, which is connected up in practice to a contrifugalspeed-governor of any ordinary type.

The valve 7 consists of a hollow cylinder open at each end and providedwith ports 8. It is connected to the lower end of the stem 6 and slidesvertically within a hollow cylindrical open-ended valve-seat or lining9, slidably mounted in the guide 4 and provided with ports 10, whichcooperate with the valveports 8. The valve-seat 9 is connected at itslower end to a stem 11, sliding in and projecting to the exteriorthrough the lower end of the casing and pivoted to an adj usting-lever12, whereby said seat may be vertically adjusted to control the flow ofsteam and speed of the engine.

The arrows in the drawing indicate the travel of the steam in passingfrom the receiving-pipe 2 to the delivery-pipe 3. The flow of. the steamis controlled by the valve 7, the stem 6 of which is connected inpractice to a governor, by which the valve is raised and loweredaccording to the speedof the speed of the engine is above normal, thevalve 7 will be'forced downward to regulate the size of the ports andreduce the steam-inlet. When it is desired to change the speed of theengineflshe valve-seat 9 is raised or lowered by the lever 12, thuschanging the position of theports 8 and 10. The usual method of changingthe speed of the engine is bylengthening or shortening the valve-stem 6,which is diflicult to do, owing to the arrangement of its connectionwith the governor-weights con- 8o trolling it. By my construction thisdifficulty is entirely overcome, as the speed of the engine may bequickly and conveniently controlled by the adjustment of the valve-seat9.

, Havingthus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a governor-valve, the combination of a casing provided withadmission and delivery ports, a, valve-guide formed integrally go withthe casing and open only at top and bottom and on the side communicatingwith said admission-port, the opposite closed side of said guide beingspaced apart from the easing to form a passage communicating with thedelivery-port and the body of the guide onlarged to form a steam-space,a hollow cylindrical valve-seat slidably mounted in the guide andprovided with ports, a hollow cylindrical valve slidably mounted in saidseat and provided with cooperating ports, a stem connected to the valveand extending to the exterior through one end of the casing forconnection with a governor, a stem connected with the valve-seat andextending to the exterior through the opposite end of said casing, andan adjusting-lever connected to the outer and lower end of saidvalve-seat stem, substantially as described.

2. In a governor-valve, the combination of a casing provided withadmission and deliv= ery ports, an open-ended valve-guide incommunication with the admission port and spaced apart from the casingat the other side to form a passage communicating with thedelivery-port, a hollow cylindrical valve-seat slidably mounted in theguide and provided with ports, a hollow cylindrical valve slidablymounted in said seat and provided with cooperating ports, a stemconnected to the valve and extending to the exterior through one end ofthe casing adapted to be connected to a nesses.
